The Quick Read: With no booking history on the house, a lender sizes your Airbnb income from a forecast, usually an appraiser’s short-term-rental analysis or a third-party projection, cuts that gross figure by a lender-set reduction, and divides what is left by the full monthly payment (principal, interest, taxes, insurance, and HOA dues). The result is your debt service coverage ratio. It is compared with the program’s minimum.
- Evidence comes first. On a purchase, the income number comes from an appraisal, a projection, or history you already hold on other rentals. It does not come from the seller’s bragging.
- The reduction hits income only. The payment stays whole, so a reduction can push a deal across a coverage floor.
- Network figures for STR: purchases up to 75% LTV on the strongest files, a 640 minimum score, and a 1.00 coverage floor on purchases, all subject to lender guidelines.
- Experience matters. Short-term-rental programs usually expect about 12 months of landlord or host experience, so confirm your lender’s stance before you write an offer.
- Passing the ratio is not the same as making money. Repairs, vacancy, management, and utilities sit outside the calculation.
Why Your Income Has to Be a Forecast
A first-time buyer has no operating history on the property, and the seller’s books are usually not yours to use. So the lender needs a number built from comparable properties, not from a track record. That is the whole reason this topic exists.

Short-term rental income is documented with a 12-month history or a market data report. Program parameters update from Lendmire’s centralized guideline source.
As of Oct 15, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, not on your W-2s or personal debt-to-income.
Conventional lenders tend to want a documented history or a tax-return trail. Traditional personal-income documentation with heavy write-offs often understates what an Airbnb really produces. That is a big reason investors drift toward DSCR. Across the wholesale network Lendmire works with, the pattern is consistent: the property’s income evidence matters more than your paycheck, so the quality of that evidence matters a great deal.
Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Key Terms Defined
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly obligation on the property, and it is the bottom half of the DSCR fraction.
DSCR (debt service coverage ratio): The property’s qualifying monthly income divided by its PITIA. A result of 1.00 means income equals the payment, no more and no less.
Gross projection: The modeled annual or monthly revenue a short-term rental could earn, before any lender reduction.
Reduction (haircut, expense factor): The percentage a lender trims from gross short-term-rental income before running the ratio. It reflects higher operating costs than a long-term rental carries. Each lender sets its own.
Comp set: The group of similar nearby short-term rentals a projection or appraisal uses to estimate your income.
Form 1007 and Form 1025: Appraisal forms for estimating market rent. Form 1007 covers one-unit properties and condos. Form 1025 covers two to four units.
LTV (loan-to-value): The loan amount as a percentage of the property’s value or price.
What Evidence Counts When There Is No History?
There are three kinds of income evidence, plus a long-term-rent fallback. Which one applies depends on whether you are buying or refinancing and on what you already operate.
| Evidence | Purchase? | Refinance? | Typical weakness |
|---|---|---|---|
| Appraiser STR analysis | Yes | Sometimes | Appraiser may lack STR comps |
| Third-party projection | Yes, widely used | Less common | Modeled, not actual bookings |
| Documented history | Only if you run other STRs | Yes, the main path | None until you own it a year |
| Long-term market rent | Fallback | Fallback | Often well below STR potential |
Some programs accept either an appraisal analysis or a projection. Some want both. A few let the lender choose, which means you may not control which number wins. Ask which source governs before you pay for any report.
Documented history means platform payout statements, management statements, or bank deposits. For a first-time buyer on a purchase, that path mostly belongs to people who already operate the same property or other short-term rentals. Refinances lean harder on history because a year of owning the property produces real numbers.
How a Projection Gets Built
A projection is a modeled estimate, not an appraisal and not a promise. AirDNA’s Rentalizer looks for comparable short-term rentals within a 10-mile radius, matched on bedrooms, bathrooms, and guest count. It weights comps by similarity and factors in seasonality, demand, and growth. The user can edit property details or hand-pick the comp set, and the tool reports a Comp Set Strength score of Low, Medium, or High.
A Low score in a thin market means few real comparables, and the projection is leaning on guesswork.
Revenue itself has a definition. AirDNA’s help center says revenue equals nightly rates plus cleaning fees, minus service fees and discounts, built from booked days times average daily rate. The same page says Airbnb host fees and other additional fees are not included in its data. So the projection is a top-line figure. It is not what lands in your pocket.
Projections also have a known weak spot. An industry blog on Rentalizer accuracy argues that blocked calendar dates can be read as demand, which tends to push estimates up. Treat that as a vendor-side argument, not a verified study. The practical lesson stands either way: model your deal on a conservative version of the projection, not the raw number.
The Sizing Walkthrough, Step by Step
Here is how a typical file moves from evidence to ratio.
1. Pick the evidence. The lender or the program decides whether the appraisal analysis, the projection, or both will be used.
2. Take the gross figure. This is the projected or documented income, converted to a monthly amount.
3. Apply the reduction. Cash Flow Diary describes lenders trimming projected revenue before the ratio is run. The size of the trim is lender-specific. It applies to projected and historical income alike.
4. Divide by full PITIA. The reduction touches only the top of the fraction. The payment is not discounted.
5. Compare to the floor. In the network Lendmire places files with, short-term-rental programs start at a 1.00 coverage floor on purchases and a 1.00 floor on refinances. Stronger ratios open better pricing and leverage.
Run the numbers on two modeled properties. The reductions below are assumptions for illustration, not any lender’s actual factor.
| Modeled reduction | Property A (1.50x gross) | Property B (1.30x gross) |
|---|---|---|
| — | 1.50x | 1.30x |
| 20% | 1.20x | 1.04x |
| 25% | 1.125x | 0.975x |
Property A clears the 1.00 floor at every level. Property B clears at 20% and slips under 1.00 at 25%. Same house, same payment, different lender, different answer.
Sub-1.00 files are not dead on arrival. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Expect lower leverage or tighter terms in return. Any outcome stays subject to credit approval and property review.
A bigger down payment helps because it lowers the payment and can lift the ratio. It never erases the caps, though. Short-term-rental purchases top out at 75% LTV on the strongest files, and refinances and cash-outs come in lower, around 70% LTV on short-term-rental collateral. Cash-out on standard long-term rentals reaches 75%, but not here. The strongest files clear two tests: enough equity and enough rental coverage. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The overstatement trap
Many first-time buyers model the deal on raw projected revenue. The underwriter uses the reduced number. If you size your offer on the gross figure, you are solving a different problem than the lender is. Back into the maximum payment your reduced income supports before you make an offer, not after.
One House, Two Ratios
A short-term-rental house often produces two coverage ratios: one from nightly income, one from long-term rent. The gap between them explains many surprises.
Form 1007 was built for long-term monthly rent. Class Valuation says it cannot support a short-term-rental appraisal on its own. McKissock explains that the form estimates monthly market rent on one-unit properties and condos, while Form 1025 covers two to four units. Either way, how income is ultimately counted falls under the lender’s scope.
So if a lender relies on the 1007 figure, long-term rent is the number that counts. That figure is often well below short-term potential. It can make the coverage floor hard to reach.
Two to four units add another wrinkle. Form 1025 is built on monthly leases, so nightly comps usually need a supplement or narrative. Ask the lender early how it handles multi-unit STR income.
Run the long-term-rent version of every deal as a stress test. If the house still lands near 1.00 on long-term rent, your downside is protected. If it collapses, you are betting entirely on the projection. That is a risk worth sizing deliberately.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What “First-Time” Changes (and What It Doesn’t)
Being new to investing and being new to short-term rentals are different problems. Lenders treat them differently, and the policy varies from program to program.
In the network, short-term-rental programs expect about 12 months of landlord or host experience, a 640 minimum score, and the coverage floors above. Most programs want stronger credit than the minimum for the best leverage. Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common, and larger loans step up. Standard programs go up to $3,000,000.
Here is what that means for you. If you have owned long-term rentals, your landlord experience may count even though you have never listed on Airbnb. If you have owned nothing, expect stricter terms or fewer programs. Lendmire’s piece Why First Time Airbnb Buyers Face Stricter DSCR Terms? walks through that tradeoff in detail.
Experience is not the only gate. Property type matters too. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in these programs, no matter how strong the income looks.
Brokers who see many lenders’ guidelines notice the same thing repeatedly. Two programs can read the same appraisal and project the same revenue, yet one wants hosting experience and the other does not. The file that goes in with the right program picked in advance tends to go smoothly. The file that waits until the appraisal comes back to discover an experience overlay does not. Pick the program before you write the offer.
If you plan to hold the property in an entity, the mechanics of vesting a DSCR loan in a new LLC matter before you apply, and LLC vesting is subject to lender program eligibility.
If the Number Comes In Low
Honestly, the stronger move is usually to fix the structure, not to hunt for a rosier projection. Work this list in order.
- Renegotiate the price. A lower price shrinks the loan and the payment. Coverage rises without touching income.
- Put more down. A bigger down payment lowers the payment, but it does not override the leverage and credit rules above.
- Check the comp set. If the tool allows edits, make sure comps match your bedrooms, bathrooms, and guest count. A weak comp set drags the estimate.
- Run the long-term-rent version. If it clears the floor on its own, you have a fallback.
- Ask about structure. Extended terms (40-year) and interest-only periods are available through select lenders in the network, and they lower the monthly obligation. ARM structures exist for investors who want them.
- Ask about the sub-1.00 path. Select lenders in the network will review coverage below 1.00, with leverage and terms adjusted.
- Ask about report timing. How long a projection stays valid varies by lender. Find out before you order it, so an aged-out report does not surprise you.
Before You Size Anything
Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Vacancy, repairs, management fees, utilities, and capital expenses sit outside the calculation. Short-term rentals carry more of those costs than long-term ones, and seasonality can leave a month or two thin. Model your own operating costs separately and conservatively.
Legality is a precondition, not a footnote. A projection assumes you are allowed to host. Confirm local rules, HOA rules, and permit requirements before you rely on any income figure.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
For a final self-check, line up your documents: platform or management statements for any rentals you already operate, your credit profile, proof of reserves, and the property’s HOA details. Then ask your lender three questions. Which evidence governs, what reduction applies, and what experience does the program expect?
If you want the broader picture first, Lendmire’s complete DSCR loans guide covers how coverage, leverage, and credit fit together.
Frequently Asked Questions
Can I qualify with an Airbnb that has no booking history?
Yes, in many programs, because the income can come from an appraiser’s analysis or a third-party projection instead of history. The lender then reduces that income and divides by the full payment. What often matters more is your own landlord or host experience, which short-term-rental programs typically expect to be about 12 months. Confirm the program’s stance before you make an offer.
Is the appraisal’s rent figure the same as my Airbnb income?
Not usually. Form 1007 is built for long-term monthly rent, so a lender relying on it will count long-term rent, not nightly income. Short-term income needs a short-term analysis, a projection, or documented history. Ask which one governs your file.
Why does the lender cut my projected income before dividing?
Short-term rentals cost more to run than long-term rentals. Lenders trim the gross figure to account for that before they run the ratio. The size of the cut is lender-specific, which is why the same property can clear one program and miss another.
Does a higher down payment fix a low coverage ratio?
It helps, because a smaller loan means a smaller payment and a higher ratio. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files have both enough equity and enough rental coverage.
Does passing the coverage test mean the Airbnb will cash-flow?
No. The ratio leaves out vacancy, repairs, management, utilities, and capex. A property can clear the floor and still run thin. Build your own operating budget before you trust the lender’s number.
